Crate ident_str 

A macro to convert string literals into identifiers. The primary use-case is to allow declarative macros to produce identifiers that are unique to each call. The alternative is to accept each identifier as an argument to the macro call, which gets unweildy with many identifiers.

Usage

macro_rules! my_macro {
    ($name: ident) => {
        ident_str::ident_str! {
            #name_a = concat!(stringify!($name), "_a"),
            #name_b = concat!(stringify!($name), "_b")
            => {
                fn #name_a() {}
                fn #name_b() {}
            }
        }
    };
}

my_macro!(foo);

expands to

fn foo_a() {}
fn foo_b() {}

Supported Macros

This crate takes advantage of MacroString and supports all macros supported by it. Those macros are:

• concat!
• stringify!
• env!
• include!
• include_str!

Ignore Variable

When any unknown variables are encountered, ident_str! will error, if that behaviour is not desired, you can add #<var> = None to the declarations:

ident_str::ident_str! {
    #ignore = None
    => #ignore
}

This exapands into

#ignore
